I was both a bit too busy and too tired physically to go out tonight. But it was a bit too bad if I didn't observe with better sky, so why not just to have some simple observation from inside my home?
M42 was my target.
I pulled out my Ranger, with my 20mm widescan, it's quite easy to see. Even the trapezium could be resolved at this magnification. Jumping with a 2x barlows, the view is better for sure. Then I pulled out my 4mm TMB planetary, and it becomes a bit too dim to view with direction vision. Averted vision does help a lot and this is by far the best view of the night.
The chromatic aberration was not a problem for deep sky observation, even at higher magnification. I was thinking whether I might go for a bigger achromat? But that won't help on solar imaging...
Anyway, it's so nice tonight since I can concentrate myself on a single target visually.
